You must at least encounter the monsters in order for it to register into your encyclopedia. To check your progress at anytime, refer to the Encyclopedia in your menu, under "Monsterpedia".

See here for Monster checklist:

Regular Monsters can all be found in dungeons. As long as you go to each area, you'll encounter them all. Strong Monsters on the other hand, only appear when Rorona's Adventure Lv. is 30 or higher. When you're selecting an area in a dungeon, the map will notify you that a "Super Dangerous Monster" if a Special Monster is in that area. They usually reside in the final area of each dungeon.

There are two types of bounties that Esty offers. The first one is for normal monsters, in which you must kill a certain amount of. The other one, are for unique monsters that only appear by accepting her requests. Those are what I refer to as Bounty Monsters. The chance for Esty to request a bounty is completely random, so you will have to either keep reloading until she requests it or sleep in your workshop until she does. That's why as a general rule, if you see her requesting a bounty, accept it if you can handle it, since they rarely appear. When you look at a dungeon map a "Target Monster" will be listed where the enemy is located.

Finally, with Dragon's, they won't start appearing until Sterk mentions about Sumi Stern in Year 3. The two Special Bosses however, will appear regardless of your level when you approach the end of their areas. They will be in the final areas of their specific dungeons.

Once you've filled up the encyclopedia with all 65 monster info, enter the menu via . The trophy should unlock shortly.
